One thing that has been bugging me since the new cam chain is the noticable tapping sound from the top end. It drove me nuts and despite some people saying it's normal for a 610 I knew that it was much more quiet when I first got the bike. So today I decided to investigate, after dumping just about all off the coolant on the garage floor I managed to take the waterpump off with the gasket in one piece ! I did not want to order parts before having a good look at the rockers. I read that the rocker shafts and bushes are prone to wear. Cheap fix is to flip the shafts 180 degrees, I reckoned at least that will help me to confirm if they are causing the noise.

Eventually got the rocker box off and marked how they (shafts) were sitting then felt for play, I pushed and pulled and it felt like there was minute play but I could not be sure. My guess was a micro milleter play could certainly translate in rocker noise. I extracted the shafts by using a 6mm bolt that screws in the side on the outside off the shaft. They came out pretty easily, then it was time to inspect.

Straight away I noticed the bushes had some bronze showing on the one side and sure enough the shafts also had a shiny vs dull side clearly showing uneven wear. I was a bit surprised at the shafts because they are made from what looks like steel ! Maybe the same steel the clutch cup washers are made off  >:D I flipped them and re installed and checked the valve clearance again. Started up and tadaa much quieter, almost like a Honda  :biggrin:

So I'll be off to the local Husky shop soon and placing an order. Only thing that bothers me is that the bushes seems to be pressed inside the rocker, although the bushes are listed it may be better just to order a complete rocker assembly and new shaft ? Any how if any 610 owners hears some top end clatter this is worth a look. I have heard that flipping them will excelerate wear so it's definetly only a temporary solution. I still think these bikes suffer from a poorly head. Parts wear just way too fast for a bike with service intervals as stated but hey no bike is perfect and I still rate it as the best ds bike I have owned.

There is nothing wrong with those bushes, and shaft does not look too bad either.
Looking at them  there seems to be wear, flipping them made the motor quiet ?

Well I did another oil change after the clutch repair and the debris are no gone, very little metal deposit on the magnetic drain plug so all looks fine.

Rocker bushes now fubar top end sounds terrible, factory moving in Italy and no stock locally and ordering online will take just as long. No riding for at least a month I would guess  :(

Order from Halls or Zipty in USA - USPS Intl = 10 days. Can ship in a padded envelope I am sure.  :thumleft:

Ja shipping is often the expense. Ask them to check the shipping cost as that sounds expensive on small parts - they often quote a ballpark figure.

Re: Metal bits in the oil ..... sorted ...... the 610 mods continue -> WATERPUMP

Eish so I go back and strip the rocker box to get to the bushes and shafts, while I'm taking it apart I have a look at the waterpump and to my dismay I find I can take the small nut off the impeller shaft by hand ! On further inspection I see that the impeller which is slotted is totally worn and just spins freely on the shaft. Looks like a pewter piece of shit. Basicly I have been riding who knows how many km's with a impeller that was not spinning, next obvious question did the bike overheat ? I had no warning light, no obvious milky residue in the oil but the coolant did look darker than normal, maybe from becoming too hot. Really don't know how to test for this except taking the head off ? The spark plug looked normal as well. Poured the coolant into a container and apart from the darker colour there was no oil slick on top.

No temp light and the fan did not come on therefore coolant could not have been too hot but a possible head gasket failure is still possible ? The motor did knock and tick even more than usual.

Coolant has to cycle past/through the sensor in order for the light and fan to register a warm condition.

Where is the pickup of the temperature sensor for the light located?

More than likely do a compression and radiator leak down test when everything is back together

Ag nee shit man  :eek7:  ek vermoed hy moes nog gedraai het anders sou hy beslis  headgasket gepop het.

Was dit nie wetter wat jou engine so laat raas het nie ?

See, if the sensor is not on the head itself, it means f'kall.
My water cooled PC suffered a water pump failure a while back. The CPU was boiling the liquid in the waterblock while the liquid in the pipes and radiator was barely warmer than usual.
Water is a poor conductor by nature.

Ja maar ek scheme jy sal kan ry met n head gasket wat gepop het. Het gelees dat dit n engine meer raserig maak, jy het hom gehoor. Mens lees te veel op die net dan gaan n mens op hol, shit deel is nou moet ek n maand sit en wonder wat presies daar aangaan tot parte arriveer. Sit alles aanmekaar en dan weer dieselfde stront. Die rockers het defnitief meer play as van te vore so hulle is gaar, impeller kon teen housing geskuur het en ook bedrae to geraas maar die engine was rerig rof en loud veral toe hy warm was. Die volgende dag het ek hom weer gestart en hy was bietjie stiller. As ek geweet het kon ek die coolant level gecheck het maar ek het dit gedrain voor ek van die stront geweet het.
